Everyone has the HD gene, but in some families an abnormal copy of the gene gets passed from parent to child. If you have a parent with Huntington's disease, you have a 50% chance of having the gene and developing the disease. Men and women are equally likely to inherit the abnormal gene.How can Huntington's disease be identified?
The definitive test for Huntington's disease is a genetic test that examines your DNA. This is done with a blood sample. This test can identify the presence of the genetic mutation (alteration) that causes Huntington's disease. The mutation is located on the HTT gene, which is found on chromosome four.
